Who should I main?

Hes super fun to play and Riot loves him.

Yasuo

You might like as he is primarily an ADC but can also be played in the mid lane. Mobility is always important to have and Lucian's really big on it. I have found him difficult to learn myself, but he always seems to be one of the better marksman picks so it would be good to learn him regardless. can also do this, but has more of a long range and safe playstyle. He can be plenty speedy as well though.

Mid/ADC overlap is usually in favor of the ADCs though, in that there are some ADCs that can midlane, but not really any midlaners that can ADC. has been tried but I think it's really niche and I don't see it being a thing in the long run.

As far as pure midlaners go it depends if you prefer mages or assassins more, as both of them are primarliy played in the midlane:

are mages that I find have simple and easy to understand kits without being dreadfully boring to play like is. With you have to worry about primarily stacking up AP with your Q, which can be done by CSing and hitting enemy champs. Your W is flat damage that hits after a delay, your E is great for both stunning and trapping, and your R is point and click to do a ton of damage. Just stack up loads of AP with him and you'll have him down in no time. Out of all of these I'd recommend him the most as he's a bit easier than to learn without necessarily sacrificing damage capability like would. might seem difficult because of his Q, but it doesn't take that long to get down. He works like in that you generally want to hit people with as many of your abilities as possible, although unlike Brand's passive it's not really necessary that you do so. Your W is great for poking, and is what you'll primarily use to CS with. His E keeps people in place and makes it easier for your Q to hit. His Q definitely has a learning curve, but if you can get it down right, it's a great source of both damage and CC. His ult is a simple death beam that works great for when people are stuck in a certain area. Definitely the hardest of my three recommendations to learn, but can really be worth it when you do get him down. is for if you'd rather be more of a support oriented midlaner. She has her W which you can use to shield teammates, and CC with her Q and E, which is what you'll use to poke down people (she is a poke champion). Once you have people snared, ult people to do your damage, although you'll find that you probably won't be leading in kill counts all the time. I would recommend for this sort of thing instead of Lux, but Riot seems hellbent on making Morgana only support, so I wouldn't recommend her in the long run as a midlaner.

I'm not as knowledgeable when it comes to assassins so I can't really give you great recommendations here, but from what I know, is on the easier side if you want to play an AD oriented assassin. isn't that hard to learn either, although I find that he can be really reliant on his ult. Don't know if is really considered an assassin or not, but I feel like he's the best of both worlds between a mage and assassin, so you might end up liking him.

udyr, because you're miserable and wanna make everyone else miserable too.

Short answer: Anyone who's fun to play. I know that seems like a cop out, but if you aren't fully invested in your champion from top to bottom you might end up dropping them down the line or making an incorrect choice.

As of right now I main Pyke since he meets my criteria of being super aggressive, high risk, and being a support. Three things I love and his lore/skins are pretty neat.

Long answer: People will probably need some information on your favorite role, playstyle, and champion design before making any specific suggestions. Looking at your match history it seems like you play a lot of ADC and Mid, what kind of playstyles do you like?

Of course, if you try them out in the training tool and you really really really like their kits and feel like you can play them well enough, then by all means go ahead and do so. In this instance though I can't really recommend champs whose functionality and viability hinge mostly on pro play.

May I suggest Syndra? Awesome damage, selfpeel, never falls too far out of meta.

Whoever you think seems cool.

Which role do you prefer playing? Do you have one?
